CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/CN2014/075008, filed on Apr. 9, 2014, which claims priority to Chinese Patent Application No. 201310636404.5, filed on Nov. 27, 2013, both of which are hereby incorporated by reference in their entireties.

TECHNICAL FIELD

The present invention relates to the field of computer technologies, and in particular, to a positioning method and apparatus.

BACKGROUND

As a latest type of terminal input equipment, touchscreen is currently the simplest and most convenient human-machine interaction manner. In the prior art, when a terminal screen displays a target application icon or target function button to be selected by a user, a commonly-used method is: the user directly taps, on the terminal screen, the target application icon or target function button to be selected. In a case in which application icons or function buttons are arranged tightly, a user may tap an unexpected icon or button by mistake and select another application icon or function button on the terminal screen. The terminal will then start the selected application icon or function button. In this case, the user will stop the selected application or function, and then tap the to-be-selected target application icon or target function button on the terminal screen. This operation needs to be performed repeatedly until the target application icon or target function button is selected.

In the prior art, however, a user directly taps a to-be-selected target application icon or function button on the screen, which cannot avoid a user from mistakenly selecting an option. When an option is tapped by mistake, an application that is opened or content that is typed, as a result of mistakenly tapping the option, needs to be closed or deleted. The operation is complex and time-consuming, and causes inconvenience to users.

DETAILED DESCRIPTION

The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a positioning method executed by a terminal, which may specifically be a mobile phone, tablet computer, player, television, computer, set top box, or another terminal. As shown in FIG. 1, the method includes:

Step 101. Detect a screen gazing operation of a user to acquire a gazed area on a screen under the gaze of the user.

Optionally, in this step, content displayed on the screen may be content that is arranged tightly and is very likely to cause a mistake in target selection. For example, as shown in FIG. 2A, the content displayed on the screen may be web page content; as shown in FIG. 2B, the content displayed on the screen may also be a menu list; as shown in FIG. 2C, the content displayed on the screen may also be entered content; as shown in FIG. 2D, the content displayed on the screen may also be desktop icons. Certainly, the content displayed on the screen may also be other content, which is not described herein.

Optionally, when a user gazes at a target on a terminal screen with his/her eyeballs, a shooting apparatus of the terminal automatically captures a movement of the user's eyeballs to acquire a gazing direction of the user's eyeballs and generate a gazed area, for example, the gazed area shown in FIG. 3. The gazed area may be a to-be-matched selection area. According to different settings, the to-be-matched selection area may be or may not be displayed on the screen. The terminal, however, saves the to-be-matched selection area to further determine the target to be selected by the user.

Optionally, a threshold range of the gazed area may be an original slice range of an object such as a gazed interface, icon, and label. For example, an icon size of the internet work operating system (Internet work Operating System, IOS) is (120 pixels*120 pixels) and the threshold range of the gazed area is a slice size of the icon. Eyeball positioning is mainly used to preselect a gazed object and generate a gazed area.

Step 102. Detect the user's hover gesture operation of pressing the screen to acquire a projection area on the screen to be pressed by the user.

For example, when the user browses a web page on the terminal, the user places a finger above a to-be-selected target on the screen of the terminal to perform an operation, and a projection area is generated on the screen of the terminal, for example, the projection area shown in FIG. 3. The projection area may be a hover touch control selection area. A size of the hover touch control selection area may be (10 pixels*10 pixels), and the hover touch selection control area will virtually expand by 20% to 80%, which may help the user select a to-be-selected object more quickly.

Step 103. When the gazed area does not include the projection area, re-detect the user's hover gesture operation of pressing the screen to acquire the projection area on the screen to be pressed by the user.

Optionally, when the terminal determines whether the gazed area includes the projection area and acquires a determining result that the gazed area does not include the projection area, in a solution provided in the embodiment of the present invention, the unexpected application icon or function button may not be started. Then, the terminal re-detects the user's hover gesture operation of pressing the screen to acquire the projection area on the screen to be pressed by the user, until the determining result that the gazed area includes the projection area is acquired. For example, when the content displayed on the screen is a menu list, the user wants to start a music player to listen to music but the projection area acquired by a hover operation of the user points to another icon in the list, such as a video player. In this case, the gazed area of the user acquired by the eyeball positioning function does not include the projection area acquired by the gesture operation of the user, and the terminal will not start the video player pointed to by the projection area.

Compared with the prior art, where, in a situation in which a user taps by mistake and selects another application icon or function button on the terminal screen, the terminal will start the selected application icon or function button, and before the terminal re-detects the user's hover gesture operation of pressing the screen, the user needs to stop an application program corresponding to the application icon or the function button that is started by mistake, in the solution provided in the embodiment of the present invention, in the situation in which the user taps by mistake, the terminal does not start the selected application icon or function button but re-detects the user's hover gesture operation of pressing the screen, which simplifies an operation of selecting a target application icon or function button and makes the operation less time-consuming.

Step 104. When the gazed area includes the projection area, process the application icon or function button included in a match area.

Optionally, in this step, the match area is the projection area.

Optionally, when the terminal determines whether the gazed area includes the projection area and acquires the determining result that the gazed area includes the projection area, the terminal may acquire that the match area between the gazed area and projection area is the projection area, and the terminal will determine to start or execute content on the screen corresponding to the projection area.

For example, when the content displayed on the screen is a menu list, the user wants to start a music player to listen to music but the projection area acquired by a hover operation of the user points to a target icon in the list, which is the music player. If the gazed area of the user acquired by the eyeball positioning function includes the projection area of the user acquired by the gesture operation, the terminal start the music player pointed to by the projection area.

The embodiment of the present invention provides a positioning method, where, a gazed area on a screen under the gaze of a user can be acquired by detecting a screen gazing operation of the user; a projection area on the screen to be pressed by the user can be acquired by detecting the user's hover gesture operation of pressing the screen; and when the gazed area does not include the projection area, the user's hover gesture operation of pressing the screen is re-detected to acquire the projection area on the screen to be pressed by the user, and when the gazed area includes the projection area, an application icon or a function button included in a match area is processed. The embodiments of the present invention may simplify an operation of selecting a target application icon or function button and make the operation less time-consuming.

An embodiment of the present invention provides a positioning method, as shown in FIG. 4, and the method includes:

Step 401. When a terminal detects that a user selects an eyeball positioning function option, enable an eyeball positioning function.

Optionally, when content displayed on a terminal screen is arranged tightly and is very likely to cause a mistake in operation, the eyeball positioning function of the terminal may be enabled. For example, when the content displayed on the screen is content such as a web page, an eBook, a menu list, or desktop icons, it may be regarded that the content is arranged tightly on the screen and the eyeball positioning function needs to be enabled.

Optionally, when the content displayed on the screen of a terminal is the content such as a web page, an eBook, a menu list, or desktop icons, it may be regarded that the content displayed on the screen is arranged tightly and the eyeball positioning function needs to be enabled. When the user enables the eyeball positioning function option and the terminal automatically detects that the eyeball positioning function option has been enabled, the terminal automatically enables the eyeball positioning function.

Step 402. The terminal sends prompt information to the user.

Optionally, the prompt information is used to prompt the user to enable the eyeball positioning function. In a situation in which the content displayed on the screen of the terminal is arranged tightly, the terminal automatically detects whether the eyeball positioning function option is enabled, and when acquiring a detection result that the eyeball positioning function option is not enabled, the terminal sends the prompt information to the user to prompt the user to enable the eyeball positioning function.

Step 403. The terminal receives information for enabling the eyeball positioning function from the user and enables the eyeball positioning function.

It should be noted that, the step 401 as well as the step 402 and step 403 are two parallel steps and represent two different manners of enabling eyeball positioning function. To enable the eyeball positioning function, only step 401 may be executed, or only step 402 and step 403 may be executed. In the figure, step 402 and step 403 are marked by dotted boxes to indicate that step 402 and step 403 are optional steps; certainly, step 401 may also be marked by a dotted box.

Step 404. The terminal detects the user's screen gazing operation to acquire a gazed area on the screen under the gaze of the user.

Optionally, this step is the same as step 101 in FIG. 1. For specific description, reference may be made to the description of step 101 and repeated description is not provided herein.

Step 405. The terminal displays the gazed area.

This step is an optional step. According to different settings, the terminal may display the gazed area on the screen, or may not display the gazed area on the screen. Nevertheless, the terminal still saves the gazed area.

Step 406. The terminal detects the user's hover gesture operation of pressing the screen to acquire a projection area on the screen to be pressed by the user.

Optionally, this step is the same as step 102 in FIG. 1. For specific description, reference may be made to the description of step 102 and repeated description is not provided herein.

Step 407. The terminal displays the projection area.

This step is an optional step. According to different settings, the terminal may display the projection area on the screen, or may not display the projection area on the screen. Nevertheless, the terminal still saves the projection area.

Step 408. The terminal determines whether the gazed area includes the projection area.

In this step, when the gazed area includes the projection area, step 409 is executed; when the gazed area does not include the projection area, step 410 is executed.

Step 409. The terminal processes an application icon or a function button included in a match area.

Optionally, this step is the same as step 104 in FIG. 1. For specific description, reference may be made to the description of step 104 and repeated description is not provided herein.

Step 410. The terminal re-detects the user's hover gesture operation of pressing the screen to acquire the projection area on the screen to be pressed by the user.

Optionally, when the terminal determines whether the gazed area includes the projection area and acquires a determining result that the gazed area does not include the projection area, in a solution provided in the embodiment of the present invention, the unexpected application icon or function button may not be started. Then, the terminal re-detects the user's hover gesture operation of pressing the screen to acquire the projection area on the screen to be pressed by the user, until the determining result that the gazed area includes the projection area is acquired. For example, when the content displayed on the screen is a menu list, the user wants to start a music player to listen to music but the projection area acquired by a hover operation of the user points to another icon in the list, such as a video player. In this case, the gazed area of the user acquired by the eyeball positioning function does not include the projection area acquired by the gesture operation of the user, and the terminal will not start the video player pointed to by the projection area.

Optionally, when the gazed area does not include the projection area, it indicates that the gazed area and the projection area do not match. In this case, the terminal re-detects the user's hover gesture operation of pressing the screen to acquire the projection area on the screen to be pressed by the user, and then re-executes the operations in step 407 to step 410, so as to accurately positioning the target to be selected by the user.

The embodiment of the present invention provides a positioning method, where, a gazed area on a screen under the gaze of a user can be acquired by detecting a screen gazing operation of the user; a projection area on the screen to be pressed by the user can be acquired by detecting the user's hover gesture operation of pressing the screen; and when the gazed area does not include the projection area, the user's hover gesture operation of pressing the screen is re-detected to acquire the projection area on the screen to be pressed by the user, and when the gazed area includes the projection area, an application icon or a function button included in a match area is processed. The embodiments of the present invention may simplify an operation of selecting a target application icon or function button and make the operation less time-consuming.
